No Symbols Loaded [Resolved]

I have a problem:
This breakpoint will not be currently hit. No symbols have been loaded for this document.

All of my breakpoints have changed to circles with question marks in them and now will not break. I dont know why this is, and it makes it very hard to debug my code without them.

Does anyone know how to fix this?

Thanks.

Are you compiling in Debug or Release? If its not Debug then try using that.

I feel silly!

Thanks for that, i dont remember changing it, but obviously i did.

Thanks for that.
